The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

Use the new helper that wraps the calls to platform_get_resource()
and devm_ioremap_resource() together.

If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.
Export the module alias information using the MODULE_DEVICE_TABLE() macro.
Before this patch:
$ modinfo drivers/gpio/gpio-ts4800.ko | grep alias
$
After this patch:
$ modinfo drivers/gpio/gpio-ts4800.ko | grep alias
alias: of:N*T*Ctechnologic,ts4800-gpioC*
alias: of:N*T*Ctechnologic,ts4800-gpio

The Kconfig for this file is:
drivers/gpio/Kconfig:config GPIO_TS4800
drivers/gpio/Kconfig: tristate "TS-4800 DIO blocks and compatibles"
...but however it does not include module.h -- it in turn gets it from
another header (gpio/driver.h) and we'd like to replace that with a
forward delcaration of "struct module;" but if we do, this file will
fail to compile.
So we fix this first to avoid putting build failures into the bisect
commit history.

Use devm_gpiochip_add_data() for GPIO registration and remove the
need of driver callback .remove.

No flags are required for bgpio_init in the TS-4800 gpio driver. This
patch set zero instead. The driver will have the same behaviour since
the & operator between the flags already resulted to zero.

The TS-4800 GPIO driver provide support for the GPIOs available
on the Technologic Sytems board FPGA. It allows to set
direction and read/write states.
It uses the generic gpio driver.
